After two days of suffering from the numerous error messages by charging my credit card (I've tried 6 different cards, both visa and master!), I've finally decided to make my payment via check. My submission finally went through and I got the invoice (just before another error message!). I looked at my invoice and it does not tell me who I should make the check payable to. I've checked "help" and the website, and also no information regarding that. Should I make it to AAMC? or AMCAS?
